CORPORATION OF RHOIDE BRAIDING'r-MACHINE CARRIER.

To all whom it may concern:

Be it known that I, Gnoncn F.

a citizen 0 MOCAHEY,

I" the United States, residing at Providence, in the county of Providence and Island, have invented certain new and useful Improvements in Braidlng-Machine Carriers, of which the followmg is a sp ecification.

This invention relates to improvements in yarn carriers for braiding has for its with an 1m controlllng machines, and object to provide such a carrier proved latch or pawl for quickly the feed of the yarn package while the same is being run at a very high velocity.

A further object of the invention is the provision of a movement pawl so arranged that a of the pawl simultaneously effects a cooperating movement of the package thereby reducing the extent of the effective operating cilitate its 7 motion of the pawl to fareleasing and engaging action.

A further object of the invention is to provide a pawl age rests w acts upon the pawl to return it upon which the .yarn pack hereby the weight of the package quickly into engaglng position to prevent the letting oil? of an excessive amount of yarn the carrier even when is running at a very high speed.

A further object of the invention is to pivotally mount the pawl beneath the yarn package on and to pro lease motio With these and other both sides of the package spindle vide a stop for limiting the re- 11 of the pawl.

objects in view, the

invention consists of certain novel features of construction, as w11l be more fully described, and

particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a. side elevation partly in section illustrating my improved construction of pawl in engagement with the teeth on the yarn package and the package resting upon the pawl.

Figure 2 as withdra is a view illustrating the pawl wn from the teeth on the yarnpackage and also as having raised the package thereon.

Flgure 3 1s a plan view on line 3-3 of Figure 1, the pawl 0 showing the pivot supports for n opposite sides of the spindle.-

I h I tlon of one means by which this result may be accomplished in a practical way With reference to the drawings, 10 desig nates the base portion of a carrier on which is mounted a vertically-disposed yarn-carrying spindle l1. Near the lower end of this spindle l have formed an enlargement 12, the upper or bearing face 13 or" which is rouniling and this enlarged portion is provided with a pair of oppositelydisposed laterally-extending pivotal trunnions 14. Extending upward from this base portion is the usual weight-carrying standard 15 on which the bottom weight 16 is slidably mounted.

A pawl or latch member 17 is provided with a rounding top plate 18 having a pair of oppositely disposed and downwardly-extending side ears 19 notched at 20 to fit over the trunnions 14: on the spindle base. On the outer end of this pawl is formed a tooth or lug 25 which is adapted to fit into the teeth 23 formed in the bottom of the package 24 to control the rotation of the latter. This top plate 18 is provided with a hole 21 through which the spindle 11 extends. The rear end wall 22 of this hole is adapted to engage the body of the spindle 11 to limit the releasing motion of the pawl so that its tooth 25 in being withdrawn can only just clear the teeth of the yarn package to prevent lost motion in the action of the pawl. The rear end of this pawl is provided with a narrow rearwardly-extend ing portion 26 having a notch 27 into which the upper end 28 of the connecting wire 29 is looped, the upper end of this wire being looped at 30 about the weight standard 15 above the bottom weight 16.

By this construction it will be seen that the yarn-package 24 rests directly upon the pawl and the tooth 25 of the pawl normally engages the front ratchet tooth 23 of the package to releasably hold the package from rotation against tension of the leading thread 31, as illustrated in Figure 1, but when more yarn is required the tension on this thread raises the bottom-weight 16 and connector 29 to lift the rear end of the pawl on its pivots 14 causing this end to raise the yarn-package and simultaneously drop the pawl tooth 25 out of engagement with the teeth of the yarn-package, by which construction it will be seen that but one-half of the releasing movement of the pawlis required, as the rest of this releasing motion is obtained by raising the package. In other words the rocking of the pawl to move its toothed end downwardly, simultaneously raises the package engaged by this tooth thereby dividing the extent of the releasing motion required of the pawl, which reduction of motion is also true of the return or engaging movement of the pawl, which latter movement, as will be seen, is also but onehalf that which would be required if it were not for the simultaneous cooperating returning movement of the package. Therefore the let-off action is extremely sensitive and quick in its action minimizing the ballooning or slackening effect on the yarn even while the carrier is running at a very high velocity.

Then again by this construction the pawl carriesthe weight of the yarn-package whereby when lifted to released position as illustrated in Figure 2, the weight of the pack- 7 age upon the pawl, has a tendency to cause the pawl to quickly return to engaging position thereby again acting upon the yarn to limit its ballooning or slackening effect while the carrier is running in its usual zigzag course about the raceway.

Another practical advantage in my improved construction is that the pawl is pro vided with widely-separated pivotal bearingson opposite sides of the spindle thus eliminating any possible cramping effect and by engaging the teeth on the package substantially on its center line, the pawl tooth will always fit squarely into the ratchet teeth. Then again by this construction the parts may be cast and the pawl simply dropped over the spindle onto its trunnions and the yarn-package set thereon. The parts of the carrier may be quickly assembled and disassembled without the use of tools.

The device is extremely simple and practical and yet inexpensive in construction and mechanical changes by its use a uniform tension of the yarn is obtained even while the carrier is running at a very high rate of speed.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the to which the device is susceptible, the invention being defined, and limited only by the terms of the appended claims.

I claim:

1. A carrier for braiding machines comprising a base member, a pawl mounted to rock on said member and carry the weight of the yarn package thereon, a packageengagmg tooth on the pawl, and a vertically slldable yarn-tension weight mounted to freely operate between predetermined limits without affecting the movement of said pawl and to rock the pawl to simultaneously lift the package and withdraw its tooth from engagement with the package only when more yarn is required.

2. A. carrier for braiding machines comprising a base member, a pawl mounted to rock on said member and carry the weight of the yarn package thereon, one end of said pawl being arranged to engage the package to normally hold it against rotation, a standard on said. base, a yarn tension weight mounted toslide freely between predetermined limits 011 said standard, a link connected to the opposite end of said pawl and positioned in the path of movement of said weight whereby when more yarn is required said weight is raised to engage said link and rock the pawl to simultaneously raise the package and also withdraw the pawl therefrom to letoff more yarn.

A carrier comprising a base member, a package spindle support, a pawl mounted to straddle said spindle and rock on said support and also carry the weight of the yarn package, a package-engaging tooth on one end of said pawl, a standardon said base, a yarn tension weight mounted to slide freely between predetermined limits on said standard, a connecting link extending fromthe opposite end of said pawl to engage said standard at a point above said weight whereby when more yarn is required said weight is caused to engage and lift said link to rock the pawl and simultaneously lift the package and so assist in withdrai'ving the pawl therefrom to let off more yarn.

In testimony whereof I afiix my signature.

GEORGE F. MoCAHEY.
